you will never get exact parent info from fastbuds. if you read between the lines its easy to figure out why. They basically take photo strain and pollen it with an auto until it becomes an auto and boom, new fast bud strain.
so to answer your question, it will likely start out with a clone of original strain and good genetics. Problem is you have no visibility into what auto they crossed it with and how that has affected the overall new product and how it might differ from the clone only or photo strain.
also since they just take it to first stage of autoland, you can assume almost all of their seeds are f1s or f2s so you will get way more variance among seeds of same strain. on positive side you will get the explosive growth typical of f1s.
wish fastbuds would be more transparent as well, but afraid if they did it would ruin part of the aura of the california super grow team and dream strains they are trying to project...with that said, i have had really good success with their zkittlez, gelato, and smoothie strains.
